Flow Control Module

Linearization and Calibration

Overview

Presently, the flow control module is to more accurately parametrize the functionality of the Flow Control Module. This project section is attempting to resolve the mystery of where inconsistencies arise that cause deviations from the standardized equations that relate head loss and flow rates which are used to dose the flow of the water treatment plant. Linearization and Calibration team goals and meeting minutes.

Methods and Results from Specific Experiments

Float valve corrosion test

• A simple test where float valve parts were left in alum and chlorine for extended periods of time to determine corrosion effects

Flow controller body design and selection

• Includes notes on the brainstorming that went into FCM parts selection and design

Flow versus head loss data collection in the turbulent range

• Experiments were conducted to establish a model for the relationship between FCM outflow and headloss associated with outflow tube position

Determining the maximum inlet shut-off pressure

• The maximum inlet pressure that the float valve can shut off was investigated in order to determine how much head there can be between the chemical stock tanks and the flow controllers

Fall 2007 Final Report

• Background on previous research
